If you're submitting a hundred applications a day, you're doing it wrong. You should get better results aiming for just a few a day, but each tailored. (Though obviously it's just not a great time right now, I'd argue not being bot-fodder and obvious chaff is extra worth it if any human ever does actually look.)
Your the first person who's told me the opposite of the advice that I've been told. It's hard to figure out which advice I should actually consider and what should be thrown out.
I'm honestly unsure how tailoring would change my resume all that much. I'm a new college grad (graduated about 2 years ago, will be 3 in May) so... Shrug. Honestly I'm wondering if I should just keep doing what I'm doing, maybe? Idk nowadays, and I doubt the automation problem is going to go away.
I mean I just don't think spamming applications pays dividends so much as exhibiting alignment with positions you actually have got a match for. That said, if you've never swung a first position post degree it's probably only going to get harder.
Especially now if you don't have real experience or interesting public facing content or code or contributions... I definitely think spamming applications is only going to help if the positions you're hitting have few applications.
I'm obviously low sample size, though. But I've mostly found roles without using my network or applying for more than a few places a day for a few weeks. But right out of college the two things that saved me were applying for positions that more experienced folks would have seen red flags (got me in the door of the field) and having experience in pertinent stuff during college.
